This is some amount of work left/forgot from device tree conversion.
Instead of checking cpu_is_xxx to determine the controller type, the
driver should use platform_device_id, which should match the device
tree compatible string.

The patch changes the driver to use platform_device_id rather than
cpu_is_xxx to determine the controller type/version.  It also updates
the platform code and device tree source accordingly.

As the result, mach/hardware.h inclusion gets removed from the driver.

It might be not good to use software defined version to identify sdma

soc name is stable enough to define the device type.

On the recent i.mx (mx25/50/53), there is a gasket inside fec
controller which needs to be enabled no matter phy works in MII
or RMII mode.

The current code enables the gasket only when phy interface is RMII.
It's broken when the driver works with a MII phy.  The patch uses
platform_device_id to distinguish the SoCs that have the gasket and
enables it on these SoCs for both MII and RMII mode.

The patch follows the implementation of gpio-mxc device registration
to break the concentrated imx-dma device registration into soc
specific setup function.  Then we can avoid the churn of "#ifdef"
and the cpu_is_mx checking on such a long list, which makes no sense,
considering more soc supports need to be added and we need to support
single image for multiple socs in the long run.

The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.

 * Add a list to save all mx2 ports references, so that
   mx2_gpio_irq_handler can walk through all interrupt status
   registers

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxc_gpio_init into mxc_gpio_probe function

 * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
   be public at all, and also make some other cleanup on
   plat-mxc/include/mach/gpio.h at the same time

And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

... together with the related devices "mx3_camera" and "mx3_sdc_fb".

"mx3_camera" doesn't fit the scheme of the other devices that just are
allocated and registered in a single function because it needs additional
care to get some dmaable memory. So currently imx31_alloc_mx3_camera
duplicates most of imx_add_platform_device_dmamask, but I'm not sure it's
worth to split the latter to be able to reuse more code.

This gets rid of mach-mx3/devices.[ch] and so several files need to be
adapted not to #include devices.h anymore.
